Can be used to configure the default log factory for the AWSJavaClientCore
and AWSJavaClientSigners. Default to JUL, unless AWSJavaClientRuntime is
present which will default it to Jakarta Commons Logging.

Used to explicitly configure the log factory. The log factory can only be
configured at most once. All subsequent configurations will have no
effect.
Note explicitly configuring the log factory will have positive
performance impact on all subsequent logging, since the specific logger
can be directly referenced instead of being searched every time.

Parameters:

factory
the log factory to be used internally by the SDK

Returns:

true if the log factory is successfully configured; false
otherwise (ie the log factory is not allowed to be configured
more than once for performance reasons.)
